(Balence team or meddler) Please share your thoughts

Can you guys enlighten me on what your thoughts are on warrior junglers? it seems like you guys intentional try to make ap and cinderhulk THE GO TO jungle enchant (besides graves and kindred). It always disappoints me as in season 4 you GOT TO PLAY THE FUN JUNGLERS LIKE Kha'Zix and Rengar when now your stuck to early game bullys or a tank. why can't riot actually try to support a carry jungler for once? its never fun playing Kha'Zix who's supposed to be a "late game carry" (going by theme but he is a strong mid game champ.) when at level 18 the enemy tank proceeds to oneshot you or your carrys while you stand there stupid like "oops no isolation ecksdee" i'm always disappointed and frustrated when you guys say that you want multiple healthy game styles but you won't support probably the must fun and healthy group of champions (divers and assassins). sorry for this mostly blind post but i'm always so frustrated as a assassin and diver jungler because you can never do shit anymore and this mage update patch has hit us pretty hard mind you (besides Zed.). i just really really want a rioter to share what the team thinks on these champions as they seem to never recieve love but when they reach decent ency you guys kill or nerf them.
